The structure and working principle of ABS pump

The function of ABS is to improve the braking performance of the whole vehicle, improve driving safety, avoid wheel locking during braking, and avoid lateral skiddling during emergency braking. The ABS system consists of an ABS module, an ABS master cylinder, a tubing and a wheel speed sensor. The main function of ABS is to understand the functions of ABS.

Not many people like this who drive a car without ABS know that if you press the brake pedal in an emergency, you can hear it, so when you use this network to ensure maximum grip between the wheels and the ground.

The automatic locking braking system, abbreviated as ABS in English, is used once the wheel is locked, the computer immediately controls the pressure regulator to release the pressure of the wheel brake cylinder, so that the constant pressure provided by the station and the main function of the braking system is to improve the braking performance of the whole vehicle, improve the safety of driving, and prevent the wheel from locking (that is, stop bearing) when braking, to ensure that the driver can control the steering when locking up, and prevent the rear axle from slipping.

The working principle of the positioning function is actually very simple, it is mainly composed of vehicle speed and wheel ABS pump sensors; The role of ABSWhat is that when the sensor detects that the wheels are locked or idling, it will control the ABS master cylinder to intervene, so that when the vehicle is in use, we can improve the safety factor of emergency braking. The vehicle employs emergency braking in an emergency, and the electric pump can also work without electricity. The brake tube on the main brake of the brake cylinder on the brake wheel is in communication and will collect and process cadea braking energy to ensure maximum grip between the wheel and the ground.

ABS controls the brake tube pressure acting on the wheel brake cylinder so that the wheels do not lock up during emergency braking, so that the vehicle remains closed during emergency braking. Your abdomen is the English abbreviation of anti-lock braking system, the full name of English is anti-lock braking systemUsually, there are two kinds of resistance during braking: one is the brake pad and the brake drum or braking system.

The role of automobile brake cylinder:

1. After pressing the brake, the main cylinder causes thrust to press the hydraulic oil to the sub-cylinder, and the piston inside the sub-cylinder begins to move under hydraulic pressure to push the brake pads;

2. The oil brake is composed of a brake master cylinder and a brake oil storage tank. They have the brake pedal attached to one end and the brake hose to the other. The brake master cylinder is stored with brake fluid, and there are oil outlets and oil inlets. When the brake is applied, the oil outlet is open and the oil inlet is closed;

3. Under the pressure of the piston of the pump body, the brake oil pipe is squeezed out of the oil pipe and flows to each brake cylinder for braking function. When the brake plate is released. The oil outlet in the brake master cylinder will be closed and the oil inlet will be opened, so that the brake oil will flow back from each brake cylinder to the brake master cylinder and return to the original state.

It is to provide power for the car, and it can also prevent the tire from locking up in the event of a breakdown, providing a strong idle speed that will not lock the tire and can drive normally.

First of all, it can prevent the car from jamming the wheels during emergency braking or emergency braking, and the vehicle will not be shocked when driving, and then it can also improve comfort and prevent tail flicking, which is a very important component.

When a large current is applied to the solenoid valve, the plunger moves to the upper end, the channel between the master cylinder and the sub-cylinder is cut off, the sub-cylinder and the hydraulic tank are connected, the brake fluid of the sub-cylinder flows into the hydraulic tank, and the braking pressure decreases. At the same time, the drive motor starts, drives the hydraulic pump to work, pressurizes the brake fluid flowing back to the hydraulic tank, and delivers it to the master cylinder in preparation for the next braking cycle. This type of hydraulic pump is called a recirculation pump.

Its function is to return the brake fluid returned from the sub-cylinder during decompression to the high-pressure end, thus preventing the brake pedal stroke from changing during ABS operation. Therefore, the hydraulic pump must be normally open during ABS operation.

In the pressure holding process, when a small current is applied to the solenoid valve, the plunger moves to a different position and all channels are cut off, thus maintaining the braking pressure. Pressurization process: After the solenoid valve is de-energized, the plunger returns to its initial position.

The master cylinder and the sub-cylinder are reconnected, and the high-pressure brake fluid at the end of the master cylinder enters the sub-cylinder again, increasing the braking pressure. The speed of pressurization and depressurization can be directly controlled through the inlet and outlet ports of the solenoid valve.

ABS operation, direct control hydraulic device simple structure, good sensitivity. In this way, the brake pedal stroke will change when the high-pressure brake fluid is returned to the master cylinder when the hydraulic pump is working, or when the brake fluid is returned from the master cylinder during pressurization. This reaction lets the driver know that the ABS is working, which is an advantage.

However, many drivers are uncomfortable with pedal response. The following is an example of a pressure regulator that reduces pedal response.

The ABS system includes a transmission hydraulic servo braking system, a brake master cylinder, a brake cylinder, a vacuum booster and pipelines, as well as an electronic control unit, sensors, pressure regulators, warning lights, etc. After the vehicle slows down, once the ABS computer detects that the wheel locking state disappears, close the main control valve and make the system enter the normal braking state. If the accumulator pressure drops below the safe limit, the red brake fault indicator and the amber ABS fault indicator illuminate.

In this case, the driver needs to use a large force to penetrate the pedal braking mode in order to brake the front and rear wheels effectively.

This is to prevent the car from locking up and is a measure to protect people's safety.

I don't know much about it, but this is also a very important part of the car, and the sensitivity is also very high, and the speed of the wheels is also very fast, which is generally controlled by computer

I don't know exactly how it works, but I know that this thing will play a big role in the car, and if it doesn't, it will have a serious impact and get into a traffic accident later.

ABS pump, Chinese translated as "anti-lock braking system". Together with airbags and seat belts, it is known as the three major inventions in the history of automobile safety. It is an automotive safety control system with the advantages of anti-slip and anti-lock.

The ABS pump is located in the engine compartment near the firewall.

The braking system on the car is a very important part of the car, sometimes the ABS system on the car will fail, after the failure, the ABS indicator light will light up to remind the driver, when the anti-lock braking system fails, although the brake pedal of the car can continue to be used, but the braking effect of the car will deteriorate, the braking distance of the car will increase, and the control performance of the car will become worse when braking.

ABS on the car is used to improve the safety of the car, when the car encounters emergency braking during driving, it is easy to appear the phenomenon of wheel locking, after the wheel is locked, the friction between the car tire and the ground will decrease, if the front wheel of the car is locked, the direction of the car will be very difficult to control, if the rear wheel of the car is locked, the car will slide sideways in the process of braking.

This pump is actually the ABS computer, that is, the core component of ABS, which is equivalent to the ECU computer in the automotive EFI engine, and the ABS pump controls the braking effect with a frequency of 8 times per second according to the signals sent by the various sensors installed on the wheels.

ABS pump is called anti-lock braking system, ABS is an improved technology based on the conventional braking device, which can be divided into two types: mechanical and electronic. ABS not only has the braking function of the ordinary braking system, but also can prevent the wheel from locking, so that the car can still steer in the braking state, ensure the stability of the braking direction of the car, and prevent the occurrence of side slip and deviation.

1. ABS is the English abbreviation of brake anti-lock braking, which is mainly to ensure that the vehicle brakes the car in the shortest distance when braking, and the vehicle also has the ability to steer and control to avoid obstacles or vehicles in time. If the ABS pump is broken, it will not affect the quality of the conventional brakes. It's just that the ABS yellow warning light on the meter will light up the alarm.

If necessary, it is best to replace the ABS pump as soon as possible. It is recommended to go to a professional repair company or a professional 4S shop for replacement.

2. The function of ABS is anti-locking, the general car begins to work at 18km h (about Ha) He is received by the ABS sensor on each tire and sent to the ABS computer board and then controlled by the ABS computer board to work The ABS pump will then pump and drain the oil at a very fast speed to achieve the effect of anti-locking.

This anti-lock braking system prevents the tires from locking up when the car brakes urgently, so that the car does not flick its tail, thus increasing safety, and is now standard in cars.

The model is different, the location is different. You can consult the 4S shop.

The effect is anti-lock braking The general car starts to work at 18km h (about Ha) He is sent to the ABS computer board by the ABS sensor on each tire to receive the signal and send it to the ABS computer board, and then the ABS computer board controls the ABS pump to work, and the ABS pump will then pump and discharge the oil at a very fast speed to achieve the effect of anti-lock braking.

ABS pump is called anti-lock braking system, generally speaking, we can be divided into mechanical and electronic two.

The ABS pump, also known as the ABS hydraulic unit, is the engine that generates power for the entire system.

It is a device that is installed on the brake pump of the car and assists the brake. The main function is to prevent braking, in the case of sudden braking, brake shoes and brake drum or disc locking, making the car slip sideways or other dangers, ABS can reduce the braking distance.

The ABS pump is a minor injury inside the part, you can go to the sales, operation and technical personnel for this similar electricity, they will explain to you the use of this pump and the process of use.

ABS is the anti-lock braking system, and the ABS pump is to make every tire not lock during emergency braking, and the maximum braking force.

ABS is the vehicle brake anti-lock braking system, and the ABS pump is a booster pump for power brakes

Melt pump (a kind of external gear pump, used for high viscosity, high pressure and high temperature medium transportation, special shaft seal design, to ensure that the air can not be in contact with ABS materials), the pump is up and down.

ABS is anti-locking, that is, when driving, the anti-lock pump should be a control, this anti-lock pump is such a pump.

ABS pump Chinese thought cumbersome is the braking system, he and airbag seat belts together known as the three major inventions of car safety fashion.

The ABS pump on the car used to have this effect, and today I finally figured it out, and those who have a car should pay attention.

ABS system, also known as anti-lock braking system, refers to the car can prevent car tires from locking up when braking. If the tires of the car lock up when braking, it is difficult to control the direction of the car, and it is easy to cause traffic accidents.

The ABS system has two working modes, one is mechanical and the other is electronic, which can not only realize the braking function of the car, but also prevent the car from locking the wheels when braking, so that the first tank of the car can still turn and drive noisily when braking. It can reduce the braking distance of the car, reduce the floating phenomenon of the car, enhance the stability of the body, reduce tire wear, and prolong the service life of the tire.

When braking in the ABS system, the brake pump will frequently squeeze the brake fluid, which will make a lot of noise. When you press the brake pedal, it will also shake. Brake fluid plays a very important role in the ABS system.

Generally speaking, the replacement cycle of brake fluid is one year, so it is recommended that the owner replace the brake fluid once a year, and do not mix different types of brake fluid when adding brake fluid.

If you find that the ABS warning light on the dashboard of the car is lit during driving, you should pull over immediately and repair it in time.

Millions of car purchase subsidies.
